HDPE管道施工方案1.1.1.适用范围适用于室外雨水管道和室外排水管道。
1.1.2.工艺原理HDPE管道安装，采用人工安装。
用非金属绳溜管，使管道放入沟槽，确认胶圈安装位置及插口的插入深度，将承口内壁清理干净，并在胶圈上涂润滑剂，对准中心轴线利用手动葫芦等提力工具逐节依次安装就位。
1.1.3.施工工艺流程及操作要点施工工艺：测量放线→机械开槽→槽底整平夯实→铺设中、粗砂基→管道安装→砼井室垫层→井室砌筑、抹面、井室防腐→胸腔填土（稳管）→闭水试验→分层回填夯实1.1.3.1.施工准备（1）技术准备：按照施工设计图纸的要求，编制施工方案，准备施工机械设备。
（2）施工放样：复测控制点及控制网和导线，测放井室位置和管道中心线。
（3）施工便道：合理布置施工便道，与沟槽保证一定的距离，满足施工需要亦不影响槽壁稳定。

由于井室中桩在施工中要被挖掉，因此在不受施工干扰、易于保护的地方测设施工控制桩，采用延长线法，测设附属构筑物位置控制桩。
施工过程中的测量主要是槽底高程的确定，机械开挖后，采用跟机测量，随挖随测，杜绝超挖现象，确保槽底高程符合设计要求，铺设砂基时，进行复测，发现问题及时处理，使管底高程控制在允许偏差范围内。
每次测量工作开始前，都要进行相邻点的复核测量。
管道中心有井室中心桩来确定，通过控制桩在管道基础上打出边线，确定管道的铺设位置。

The outline and dimension of the reactor R6300 is shown in sketch 1.2.吊装方案Lifting Scheme反应器R6300的吊装采用我公司从英国Bidlift Limited引进的液压顶升门式吊装系统，按我公司目前的配置，这套系统的最大吊装能力为2400t，最大吊装高度为140m。
对本工程而言，只需用这套系统的部分液压千斤顶和部分构架即可满足反应器R6300的吊装要求。
因此，反应器R6300的吊装采用液压顶升门式吊装系统主吊，用1台250t履带吊车配合溜尾的吊装方案。
The lifting of the reactor R6300 will be performed with the Kramo climbing jack system introduced from Bidlift Limited, U.K by our company. This system has a maximum lifting capacity of 2,400t and a maximum lifting height of 140m according to the present configuration of the system we ordered. For this project, only part of the system is needed to perform the lift of the reactor R6300. Therefore, the system is to be used as main lifting gear for the lift of the reactor R6300 and a 400t crawler crane for tailing.反应器的吊装操作过程见下面的示意图：The lifting process of the reactor is shown in the following sketches.a. Start Liftingb．Jacks are climbing up while tailing in crane carries the reactor forwardc. with the help of the tailing in crane, the reactor is lifted from horizontal position to vertical position.d．jacks continue climbing until the bottom of the reactor is lifted over the top surface of the foundation.e.the reactor is moved over the foundation by horizontally-moving jacksf. the reactor is lowered in place3.吊装平面布置Lifting Plan Layout反应器R6300在现场的摆放位置及方向见图2。
The position and direction of Reactor R-6300 laid on site are shown in sketch 2 below.Sketch 2吊装的平面布置及拖拉绳地锚的位置见下面的图3。
The plan layout for the lift and the locations of deadman are shown in sketch 3 below.图34．液压吊装系统的安装Installation of Climbling Jack System4.1 反应器R6300吊装所需的液压吊装系统应尽可能在料场组装。
Climbing jack system used for lifting reactor R6300 should be assembled in laydown area as much as possible.4.2 桅杆底座在安装时需要一名测量员对桅杆底座的就位进行精确测量。
One surveyor should be assigned to make a precise surveying to positioning of mast base when mast base installed.4.3 每节12m长的桅杆节重12吨，每根桅杆需要安装7节，总高84米。
Each mast section of 12m long weighs 12t, and seven of such sections are needed to build one 84m mast tower.4.4 设备应从料场直接运抵安装现场并就位，以避免二次倒运。
Move equipment from laydown area and position immediately to avoid double handling.4.5 设置临时地锚。
Temporary deadmen to be positioned.4.6 安装桅杆至24m的高度。
Erect mast to 24m4.7 第三段桅杆节吊装组对前系临时拖拉绳。
Section No.3 is to be fitted by temporary guys before lifting.4.8 第三段桅杆吊装就位后稍稍拉紧临时拖拉绳。
Lift Section No.3 into position, and then run out Temp. guys and lightly tension.4.9 安装临时对拉绳并检查桅杆的垂直度。
Fit temporary cross guying and check mast verticality采用临时拉绳的原因是因为基础高于地坪24米，起重梁将在36米高处安装至桅杆中间。
正常情况下应在12米高处安装。
起重梁一方面联结桅杆另一方面起着压重作用以保持吊装系统的稳定性。
The temp. guying to be used because the foundation is 24m above ground. The lifting beam is to be fitted between the masts at the 36m level. Normally this would be done at the 12m level. The lifting beam connects the masts and also acts as ballast giving the rig stability.4.10 在28米高处将400吨千斤顶及圆形垫板安装到桅杆上。
Fit 400t jacks and articulating plates to mast at 28m level.4.11 将起重梁安装至6m高的临时塔架上，在此位置将吊装系统的多种附属设备安装到起重梁上。
在安装附件后起重梁的重量将达到60吨，就位后高30米。
Position lift beam on stools (6m mast sections) and fully dress before lifting into position.Dressed weight 60t to 30m.4.12 将起重梁从临时塔架移至正式吊装的桅杆上，因高度较高，在36m高处安装起重梁将是一项艰巨的工作。
Position the beam between the masts at 26m level and dress, but because of the height, this will make it a difficult procedure.4.13 起重梁就位并使千斤顶受力。
